Housing In Kibera's Soweto East Informal Settlement, Kenya: A Socio-Technical Evaluation, Tiernan Brennan
Housing In Kibera's Soweto East Informal Settlement, Kenya: A Socio-Technical Evaluation, Tiernan Brennan
Masters
In 2003, the Kenya Slum Upgrading Programme (KENSUP) was launched in partnership with UN-Habitat and the Government of Kenya (GoK) to improve the livelihoods of people in Kenya by 2020 through the provision of improved shelter, infrastructure, land tenure and income generation. Kibera is an informal settlement in Kenya where varying housing typologies and traditional vernacular-style designs coexist with modern housing units. Soweto East was one of eighteen villages located in Kibera selected for KENSUP’s first major housing development initiative. Soweto East was selected from a screening of several housing projects that could be subjected to a socio-technical (STE). The …
Design And Development Of A Low Cost Platform To Facilitate Post-Stroke Rehabilitation Of The Elbow/Shoulder Region, Stephen Curran
Design And Development Of A Low Cost Platform To Facilitate Post-Stroke Rehabilitation Of The Elbow/Shoulder Region, Stephen Curran
Masters
For post-stroke rehabilitation of the upper limbs, increased amounts of therapy are directly related to improved rehabilitation outcomes. As such, a low cost therapy platform is proposed suitable for facilitating active therapy and administering activeassist therapy to the shoulder/elbow region of the upper limbs of individuals post-stroke in a local clinic or domestic setting. Enabling a person to undergo intensive rehabilitation therapy outside of a rehabilitation hospital setting permits the amount of therapy administered to be maximised. While studies have shown that technological approaches to post-stroke rehabilitation do not produce better outcomes than equal amounts of traditional therapy in a …
Numerical Prediction Of Primary And Secondary Flows In A Ranque-Hilsch Vortex Tube, Ronan Oliver
Numerical Prediction Of Primary And Secondary Flows In A Ranque-Hilsch Vortex Tube, Ronan Oliver
Masters
The primary aim of this project is to obtain a fundamental understanding of the fluid dynamics and thermodynamics of the primary and secondary flows in a Ranque-Hilsch Vortex Tube (RHVT). These flows are highly complex and are three dimensional, compressible and viscous in nature. To obtain an understanding of these, a state of the art Computational Fluid Dynamics (CFD) software package is applied for flow prediction with advanced turbulence models, and is employed to predict the primary and secondary flows in a RHVT. The models that are used include : the k-e model, the SST model by Menter, and the …

Electroanalysis Using Differential Pulse Methods And Stripping Techniques., Enda Howard
Masters
Application of a differential pulse waveform to a microelectrode or a rotating disk electrode results in a peaked response for amperometric redox reactions. Based on these observations models were proposed and tested for these methods. Simulations of the models were carried out by inputting the relevant equations into Microsoft Excel. The microelectrode study revealed a good correlation between one model and the numerical derivative of the current following a linear sweep potential waveform. Experimentally the derivative can be obtained numerically following a linear sweep. The alternative differential pulse waveform requires more sophisticated equipment and the response can be affected by …
